SE Synchronous Servo Motors

The Bosch Rexroth SE Synchronous Servo Motors series is a family of brushless permanent-magnet servo motors developed for Servodyn drive systems and intended for position and speed-controlled applications in mechanical engineering. The motors use rare-earth rotor magnets, electronic commutation, an integrated brushless tachogenerator, and a commutation sensor, which gives the series low rotor inertia and supports high dynamic response in servo operation. The range includes multiple construction sizes and lengths, with standard motors supplied in flange-mounted form and available options such as keyed shafts, integrated holding brakes, encoder attachment provisions, and special versions including oil-tight driving-end designs. Across the series, the motors use enclosed housings with protection ratings up to IP67 on many versions, natural convection cooling, integrated thermal monitoring, and bearing service life specified above 20,000 hours. The SE series is designed as a configurable servo motor platform for applications that require fast response, smooth running, long service life, and compatibility with Bosch Servodyn inverter systems.
